I Have few questions about owning Using 2 IPhone devices at the same time. 1. if you had old iphone and you are buying a new one so it will let you back-up the data from the old iphone to the new one. Will it let me do that in 2 new iphones (I'll plug the first one and back it up, and then plug the second one- will it ask me to backup again)? 2. Can i use two Iphones with the same computer and ITunes acount? 3. data: everytime i will connect one of the iphones it will transfer all the app-datas (game saving etc) to the ITunes and then it will transfer the same data to the second one when i will plug it? for example: When i bought the new iphones i transfered them both app data of a curtein game and i was in level 10. in one iphone i proceeded to level 20, and in the other i reached only 15. when i will plug the first iphone (20) to the computer and then the second one (15) it will transfer the seconf one (15) the ata from the first one (20) and it will get evel 20 too?
